Incident Overview
While landing on a 30-foot-wide runway under steady crosswind conditions, the aircraft encountered an unexpected gust of wind. The pilot attempted to correct for the unfavorable wind conditions, but the efforts were not adequate to prevent the aircraft from departing the side of the runway.
Sequence of Events
After departing the runway surface, the aircraft entered a swampy area adjacent to the runway. The aircraft subsequently nosed over in approximately nine inches of water. The pilot later realized that wind funneling between buildings and trees located alongside the runway had created a funnel effect, producing localized areas of crosswind gusts. This phenomenon likely contributed to the unexpected gust encountered during the landing.
Contributing Factors
The pilot's corrective actions were insufficient to maintain directional control when the unexpected gust occurred. The funneling of wind between structures and vegetation alongside the runway resulted in gusty crosswind conditions that were not fully anticipated.
